The approach for cleaning surgical instruments can be the same if the presence of pathological prions (including the prions of vCJD Creutzfeld-Jakob disease) however the attention to detail is more important. It is known, that prions are unusually resistant to disinfection and sterilization by the physical and chemical methods used for decontamination of infectious pathogens. It is a difficult task to gain a consensus opinion on what constitutes optimal and practical conditions for decontamination of prions. Numerous studies have been conducted, but they do not reflect the reprocessing procedures for surgical instruments in a clinical setting. The clinical setting is critical for iatrogenic transmission, the passing of a disease from an infected individual or group to a previously uninfected individual or group. The method of reprocessing prion contaminated surgical instruments includes (1) decontamination by NaOH or NaOCl for 30 or 60 minutes followed by GL-autoclaving at 121°C for 30 minutes, (2) cleaning and (3) routine PL-sterilizing at 134°C. It is known that some surgical instruments cannot be decontaminated by heat and moisture. Disinfectants have been widely used for this purpose even although the disinfectants are ineffective. The most common practice believes that the only completely safe way to prevent transmission of vCJD is to use single-use surgical instruments. Because of the pervasive distribution of these infectious proteins and the long incubation time of the disease, reprocessing cleaning surgical instruments has been identified as a high risk factor for nosocomial transmission of vCJD. Research has shown that the agent of the vCJD disease, an infectious prion protein, is extremely resistant to today’s sterilization methods; therefore, the argument, “It does not matter if instruments are 100 percent clean, as they will be sterilized,” is definitely no longer valid. Today, we understand that cleaning surgical instruments is as important as the sterilizing the surgical instruments.
Today’s surgical instrument cleaning process requires increasingly sophisticated surgical instrument cleaning concentrates. Detergents, which are used in these processes, can be mild, with a neutral pH, or they may be more aggressive, with values in the alkaline range of the pH scale. A number of hospitals and surgical centers are effectively using neutral pH “combination” enzymatic enzyme detergent cleaners for reprocessing surgical instruments. The “combination” 4 enzyme detergent cleaners provide optimal cleaning as well as the highest possible level of care for surgical instruments and scopes. The manufacturers of surgical instruments strongly recommend the use of Neutral pH cleaners to enhance the passive layer of instrument protection. The early prion inactivation approach, using a high concentrate of sodium hydroxide solution or sodium hypochlorite combined with long holding times, is generally lethal for medical surgical instruments and washer-decontaminators- disinfectors. Recently, researchers have been looking is a minimally destructive method to decontaminate surgical instruments potentially contaminated with prions. The use of “combination” 4 enzyme detergent surgical instrument cleaners has offered the highest level of cleaning outcomes.
